Abstract Desertification is one of the fundamental problems that threaten many arid and semi-arid areas. The formulation of the United Nation Convention to Combat Desertification (UNCCD), adopted in Paris, 1994 and ratified in 1996, with the active participation of Egypt, gave emphasis on combating the major threats to sustainability of dry lands. Recently, different models were developed to fo...
Desertification is known as a major crisis in arid regions of Isfahan province. This study aimed to assess the performance of three main desertification models including MEDALUS, MICD and FAO-UNEP for mapping desertification severity in the hotspot of Jarghuyeh region, eastern Isfahan. Different desertification indicators and their related indices were chosen based on the characteristics of the...

Natural and anthropogenic causes jointly lead to land degradation eventually desertification, which occurs in arid, semiarid, dry subhumid areas. Furthermore, extended drought periods may cause soil exposure erosion, and, finally, desertification. Several climatic, geological, hydrological, physiographic, biological, as well human factors contribute This paper presents a methodological procedur...
several models have been developed to estimate land degradation rate and evaluate desertification severity. this study attempts to apply the medalus (mediterranean desertification and land use) model by considering existing conditions in the hamoun wetland, located in south-eastern iran. at first identification of the main factors affecting the desertification phenomenon was attempted, based on...
Aeolian desertification is a kind of land degradation that is characterized by aeolian activity, resulting from the responses of land ecosystems to climate change and anthropogenic disturbances. The source areas of the Yangtze and Yellow Rivers are typical regions of China’s Tibetan Plateau affected by aeolian desertification. We assessed the vulnerability of these areas to aeolian desertificat...
